Arbuscular mycorrhizae in metalliferous and aluminum-rich soils.

Arbuscular mycorrhizal fungi (AMF) are potentially present in most trace metal- and Al-hyperaccumulating plant genera in metalliferous and Al-rich soils, but direct confirmation under natural conditions is limited.

• Why it matters: Understanding AMF's role in these environments is crucial because high concentrations of toxic elements restrict plant growth, and AM symbiosis may help mitigate these stresses, aiding conservation and restoration efforts.
• What they did: The review synthesizes evidence from global ecosystems, highlighting mechanisms like element sequestration and improved plant nutrition, and examines how AMF community composition varies with environmental factors and fungal identity.
• The result: Findings suggest that AMF can alleviate metal and Al toxicity, but their diversity and function in these soils require further research to enhance ecological management and plant resilience strategies.
